Hi Volker,

The interface looks like this:

# ifconfig tun6
tun6: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1500
        options=80000<LINKSTATE>
        inet 10.63.255.77 --> 10.64.64.64 netmask 0xffffffff 
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        Opened by PID 1041

but the WAN addr is valid (seems to be NAT'ed) in the APN:

# lynx -dump myip.nl | fgrep WAN
   WAN IP adres: 82.113.99.77

Thanks

	matthias
